OpenBSD's ypldap daemon provides YP maps using an LDAP backend. It was introduced with OpenBSD 4.4 but doesn't seem to have received much exposure within the community. I've been meaning to convert one of our bastion systems from using local accounts to LDAP, mainly for convenience.

The migration went smoothly except for the lack of a netid.byname mapping. Pierre-Yves Ritschard ([email protected]) told me this is high on his to-do list. Without this mapping, sudo is unable to getpwuid(). Therefore, any accounts requiring sudo rights (read: administrators) will need to remain as local accounts until this is resolved.

The vast majority of this write-up was taken almost verbatim from a similar posting at the Helion-Prime Solutions blog. I've filled in some missing bits with regards to the sudo issue as well as ypbind issues over non-broadcast segments.
